It may seem odd to think about offering birds a roost during the winter.
But the fact is that even in snowy climates there are many birds that
do in fact stay out the winter. If you’re a bird lover, it’s
simple to get the birds that are in your area to frequent your yard.
You just need to put up a few winter bird houses and you’ll
have a flock of tenants in no time.
So what makes winter bird houses different from ordinary
ones? Well, for starters they’re designed almost completely
opposite from an ordinary bird house. Ordinary bird houses are built
to provide good ventilation so that the birds will not overheat inside
them. That would be counterproductive in the winter, when you’re
trying to keep the birds from freezing. So while a winter bird house
will have vents, they are generally smaller, and positioned near the
bottom to prevent the warm air from leaking out of them.
Another major difference between summer and winter bird
houses is the entrance positioning. In a summer birdhouse the entrance
is at the top, to allow better circulation. In a winter birdhouse
the vent is usually placed at the bottom of the house. Again, this
helps prevent the hot air inside from escaping out the vent. Winter
bird houses are often insulated with carpeting or extra thick wood
as well, this helps keep the body heat of the birds inside the house
rather than releasing it into the air.
Finally, winter bird houses are larger than their summer
cousins. This is because to stay warm, a dozen or more birds may crowd
into a small space and share body heat during the winter. A summer
bird house is typically sized for just a few birds, but if you want
to give the birds a comfortable place to live during the winter, it’s
imperative that you provide enough space for multiple birds.
